5 Alternatives to the OUPES Mega 1 Portable Power Station (Including Better Fits for Some Buyers)

The OUPES Mega 1 looks appealing on paper: 1024Wh of LiFePO4 storage, 2000W output, rapid charging and expandable capacity for £399.99. But shoppers often look for alternatives when it’s out of stock, when they want a more trusted brand, or when they realise they need either a cheaper backup for short outages or a larger unit for proper home resilience. In the UK, where winter solar generation is weak and electricity prices still make blackout backup and load-shifting attractive, the right choice depends on how much capacity, output and reliability you actually need.

If you’re comparing the OUPES Mega 1 against alternatives, the first thing to notice is that it sits in a very aggressive price-to-spec bracket. £399.99 for 1024Wh and 2000W is strong value, but the market around it is a mix of smaller budget units, premium mid-range models, and expandable systems that may cost more upfront but make more sense for home backup. Here’s how the main alternatives stack up in practical terms.

Jackery Explorer 500 — £305.00

At first glance, the Jackery Explorer 500 is only about £95 cheaper than the OUPES, but it gives you far less battery for the money: 518Wh versus 1024Wh. That means the OUPES has roughly double the stored energy, so in real-world use it can run a fridge, router, lights, or laptop for much longer during a power cut. Jackery’s 500W AC output is also much lower than the OUPES’s 2000W rating, so it’s fine for modest camping loads and small electronics, but not ideal if you want to start appliances with higher surge demands or run multiple household devices at once.

The practical upside of the Jackery is that it’s a well-known brand with a reputation for consistent build quality and good app-free simplicity. It’s often a better fit for occasional camping, weekend trips, or as a lightweight emergency unit for phones, cameras, and small devices. In terms of build, Jackery generally feels tidy and dependable, though the Explorer 500 is an older design and lacks the expansion potential of the OUPES. There’s no path to scaling it to 5kWh, so if your needs grow, you’ll be buying a whole new system.

Verdict: choose the Jackery only if you value brand trust and portability more than capacity. For UK home backup, the OUPES is vastly better value per watt-hour.

EcoFlow RIVER 2 Pro — £499.00

The EcoFlow RIVER 2 Pro costs about £99 more than the OUPES, but it brings a very polished package: 768Wh of LiFePO4 storage, fast charging, and up to 800W AC output with X-Boost to 1600W on some loads. That makes it a strong choice for people who want a premium-feeling portable power station for camping, van life, or light home backup. The biggest difference is not just capacity — the OUPES has more battery at 1024Wh — but the overall ecosystem and charging experience. EcoFlow is known for fast recharge times, strong app support, and generally better product maturity than many budget brands.

However, the lower capacity matters. In a UK power cut, 768Wh can disappear quickly if you’re running a broadband router, a lamp, charging devices, and a small appliance. The OUPES gives you more breathing room, especially if you want to keep essentials going through an evening outage. Build quality on the EcoFlow is typically excellent, with a more refined product feel and strong thermal management. If you’re comparing pure specs, though, the OUPES looks better on capacity and output per pound.

Verdict: pick the EcoFlow RIVER 2 Pro if you want a premium portable unit and don’t mind paying more for a smaller battery. If value and runtime matter more, the OUPES wins.

EcoFlow RIVER 2 Pro (X-Boost 1600W version) — £499.00

This version is effectively the same class as the standard RIVER 2 Pro, but the headline difference is the X-Boost marketing around higher-output compatibility. In practice, this can help with some resistive loads, but it does not change the underlying battery size: 768Wh is still 25% smaller than the OUPES Mega 1. That means the OUPES remains the better choice if you care about how long your backup lasts rather than just whether a device can briefly start.

The price premium over the OUPES is hard to justify unless you specifically want EcoFlow’s software, reputation, or a smaller, more portable form factor. For camping, the EcoFlow is neat and easy to carry. For home resilience, the OUPES is the better value because UK households usually need runtime more than peak gimmicks. A 1kWh class battery is far more useful when winter solar is poor and you’re trying to bridge evening peaks or short outages without touching the grid.

Verdict: the EcoFlow makes sense if you want a refined, portable brand-name unit. The OUPES is the smarter buy for most budget-conscious buyers.

EcoFlow DELTA 2 — £549.00

The DELTA 2 is the most serious alternative here for home backup. It costs about £149 more than the OUPES, but it also moves you into a more capable category: 1–3kWh expandable capacity, LFP chemistry, and a design that’s much closer to a true household backup solution. If you’re looking to power more than just phones and laptops — think router, lighting, TV, small kitchen appliances, or even longer outage resilience — the DELTA 2 is the stronger long-term platform.

The key practical advantage is expandability. The OUPES can expand to 5kWh, which is impressive, but EcoFlow’s DELTA ecosystem is more established and widely supported. That matters if you want a product that feels easier to integrate, easier to resell, and more proven over time. Build quality is generally excellent, with a premium enclosure and solid power electronics. The downside is the higher upfront cost. If you only need a portable battery for occasional camping or short blackout cover, you may not recover the extra spend in utility.

For UK users, this is the sort of unit that can make sense if you already have solar and want to store daytime generation for evening use, especially during spring and summer when panels produce more. In winter, though, even expandable batteries only help if you can recharge them regularly.

Verdict: choose the DELTA 2 if you want a more future-proof home backup system and are willing to pay more for it. The OUPES is better value for entry-level buyers.

VTOMAN Jump 600X — £179.99

The VTOMAN Jump 600X is the budget option here, and it’s dramatically cheaper than the OUPES — about £220 less. But that price gap reflects a much smaller battery: 299Wh versus 1024Wh. In practical terms, the VTOMAN is best thought of as a compact emergency and travel power bank rather than a serious household backup station. It can handle phones, tablets, small lights, routers, and some low-power DC loads, but it will run out of steam much faster than the OUPES.

The upside is portability and value. If you only want something to keep essentials alive during a short outage or to support light camping, the VTOMAN is an attractive buy. The 600W output with 1200W surge is useful for modest devices, and the USB-C and regulated DC outputs are handy. Build quality is generally acceptable for the price, but it doesn’t have the same sense of robustness, capacity headroom, or long-duration usefulness as the OUPES. For a UK household, the biggest limitation is simply runtime: 299Wh is enough for a few hours of light use, not a meaningful overnight backup.

Verdict: choose the VTOMAN if budget is the overriding factor and you only need a small emergency unit. If you want real outage coverage, spend more and get the OUPES.

Overall value comparison

On pure value, the OUPES Mega 1 is the standout because it combines 1024Wh, 2000W output, LiFePO4 chemistry and fast charging at a price that undercuts many weaker rivals. The Jackery is more expensive per unit of energy and much lower in output. The EcoFlow RIVER 2 Pro is a premium compact option, but you pay more for less capacity. The DELTA 2 is the strongest step up if you want a genuine home-backup platform, while the VTOMAN is the cheapest way to get basic emergency power.

If you’re in the UK and trying to reduce electricity bills, the most important question is whether you want backup power or usable stored energy. A 1kWh battery can be meaningful for evening load shifting, but only if you’re recharging it efficiently — ideally from solar in spring and summer, or from cheap off-peak tariffs if you have them. In that context, the OUPES Mega 1 hits a very useful middle ground: big enough to matter, affordable enough to buy, and expandable enough to grow with your needs.

So the best alternative depends on your priorities. If you want the cheapest small backup, pick VTOMAN. If you want brand trust and simplicity, Jackery is the safe pick. If you want premium portability, EcoFlow RIVER 2 Pro is strong. If you want a more serious home backup platform, EcoFlow DELTA 2 is the upgrade. But if you want the best balance of price, capacity and output, the OUPES Mega 1 still looks hard to beat.
